Heating appliance



Nov. 26, 1929. A. 1.. OAKLEY HEATING APPLIANCE Filed NOV. 10, 1928 Patented Nov. 26, 1929 UNITED STATES PATENT OFFECE' HEATING APPLIANCE Application filed November 10, 1928.

This invention pertains to heaters and more particularly to appliances designed for heating rooms and the like.

One of the objects of this invention is to provide a heater of simple construction, which is capable of rapidly heating the air in a room and projecting the same in such a manner as to cause a circulation thereof.

Another object is to provide such a heater m which will not only act to induce a circulation of heated air, but which will also act as a radiator.

Another object is to provide such a heater which may be controlled in a simple manner.

Another object is to provide aheater of the type described, having an auxiliary heating unit which may be used by itself when only a slight amount of heat is desired.

Further objects will appear from the fol- 29 lowing description, taken in connection with the accompanying drawing, in which Figure l is a plan view of a heater embodying this invention; and

Figure 2 is a section on line 22 of Fig- 535 ure 1.

Referring to the drawing, 1 designates a base or stand having a top 2 which is imperforate except for a flanged opening 3 and an ignition hole. Mounted in the open- 39 ing 8 is a flue A, which extends upwardly from said opening and turns forwardly at its top as illustrated in the drawing.

Mounted on the base 1 and below the opening 3 is a heating unit 5. In the embodiment illustrated in the drawing, the unit 5 is shown as a gas burner unit, though it is understood, of course, that other types of heating units may be used. The heating unit 5 may be controlled in the usual manner by a valve 6 communicating with a fuel supply pipe 7. A

small burner 8 in the nature of a simmering burner, supplied by a pipe 9 controlled by a valve 10 and taking its supply of fuel from the pipe 7, is also mounted on the base 1 and positioned underneath the rear portion of the opening 3. An ignition hole 12 in the base may be provided for lighting the burner.

It will be noted that the heating unit 5 and also the small burner 8 are mounted 59 under the rearward portion of the flue 4,

which extends upwardly thereover and then turns forwardly at its top. When the heating unit is in operation the air heated thereby will rise through the flue 4 and be guided thereby so that as it emergesfrom the flue 4 it will be projected forwardly into the room. A strong draft is thus created so that a rapid flow of heated air into the room is obtained, and this air is projected at a considerable velocity into the room so that a definite cir culation is set up. Such circulation will eventually pass all of the air in the room through the'heater so that the room may be warmed thereby.

It will also be noted that the rear wall 11 of the flue at leans over the heating unit. Accordingly this portion of the flue willbecome highly heated. Especially in the case of a flamingheating unit, such as a gas burner, the hot flame will tend to heat the wall 11 to a high temperature. This wall then not only assists in the combustion of the gas, but provides a heat radiating surface which radiates heat rearwardly and thereby adds its effect toward heating the air in the room.

The small unit 8, being positioned directly under the forwardly leaning portion of the wall 11, will tend to heat that portion of the flue even when the main burner 5 is not operating. Accordingly, the small burner unit may be used to supply a small quantity of heat when such is desired.

It will be seen, therefore, that this invention provides a simple and compact heating unit and one which is economical to manufacture. The unit lends itself to application of heat in places which are relatively inaccessible to heat supplied by other types of heating plants. The quantity of heat can be controlled very accurately by control of the burners 5 and 8. The arrangement of flue directly over the burner tends to create a strong draft, which passes a large quantity of air through the heater.

It is obvious that various changes may be made, within the scope of the appended claims, in the details of construction without departing from the spirit of this invention. It is, therefore, to be understood that this invention is not to be limited to the specific details shown and/0r described.

Having thus described the invention, what is claimed is:

1. A room heater, comprising, a heating unit, and a flue extending upwardly and positioned eccentrically over said unit and having a wall leaning over said unit whereby the heat from said unit is concentrated on said leaning wall so as to be heated thereby, said flue turning forwardly at its upper end.

2. A room heater, comprising, a flaming heating unit, a flue extending upwardly directly over said unit and having a wall leaning over said unit whereby the flame from said unit is concentrated on said leaning wall so as to be heated thereby, said flue turning forwardly at its upper end, and a heater of reduced intensity associated with said unit and positioned below said wall.

3. A room heater, comprising, an extending flue directed upwardly and forwardly substantially throughout its extent, and a heating unit positioned below the rear portion of said flue so as to heat the rear wall thereof and cause a strong upward flow of heated air therethrough.

4. A room heater, comprising, an extending flue directed upwardly and forwardly substantiall throughout its extent, a heating unit positioned below the rear portion of said flue so as to heat the rear wall thereof and cause a strong u ward flow of heated air therethrough, anc a low-intensity heating Enit positioned under the rear wall of said In testimony whereof I afiix my signature this 7th day of November, 1928.
